208 IOWA STUDIES IN NATURAL HISTORY 
tor. Small patches of coral reef were conveniently located, 
both in English and Falmouth Harbors; while Willoughby Bay 
had a fine stretch of reef extending almost across the entrance. 
We had the opportunity, however, to study the ordinary reef 
corals at Barbados and felt that our time at Antigua could be 
more profitably used mm the study of other groups. One form, 
Mancina, was common in the quiet waters of Falmouth Harbor, 
while Orbicella, Astrwoides, Porites, ete. were growing in quite 
shallow water near the shore. 
We were much struck with the beauty of a bright purplish 
blue Porites growing on the shoals near Rocky Point. I had 
never seen corals of this color before. The bright blue, however, 
disappeared quickly in alcohol, but persists in some dried speci- 
mens that we brought back with us. 
Aleyonarians were by no means so common as at Barbados. 
We saw many of the ordinary gorgonians along the reefs in Wil- 
loughby Bay, but not mn such dense and extensive patches as 
off Hastings, Barbados. Several fine specimens of Xiphorgorgia 
were secured. ‘The yellow variety of Rhipidigorgia flabellum 
was common, while the purple sea-fans were scarce. As indi- 
cated before, I am inclined to believe that these two forms are 
specifically distinct. There is, beside the marked color differ-_ 
ence a great disparity mn size. Im my experience the yellow 
form is always small, ordinarily less than a foot high, while the 
purple form is from two to four feet high when fully grown. 
The pattern of the branches in both cases is more finely reticu- 
late than in any other species that I have seen. No representa- 
tives of the Pennatulacex, of the Aleyonacea, nor of antipath- 
arians were secured. 
The only representative of Ctenophora was a species of 
Berée which was collected at night, being very conspicuous on 
account of its brilliant phosphorescence. 
A number of interesting and beautiful anemones were col- 
lected and preserved by Miss Van Wagenen, who has kindly 
placed her notes at my disposal. The largest and most beautiful 
form was Condylactis gigantea with a spread of twelve to four- 
teen inches and a height of four to seven inches. The tentacles 
were tubular, smooth and very translucent, colored a delicate 
green tipped with purple, while the body wall was cadmium
